RUBBER BAND CUSHION SHOE SOLE PRESS Filed July 12, 192s' ZELL/m Patented Oct. 27, 1931 GULLEN L. HUNTOON, F LOS ANGELES, CALIFORNIA RUBBER BAND CUSHION SHOEl SOLE PRESS Appli-cation filed July 12,

Thisinvention relates to improvements of a device for applying shoe soles to footwear and may be considered as an improvement over'the device disclosed in my prior Patent Number 1,634,996, issued Julyy 5th, 1927.

AnA object of the invention is to provide a form of screw press, having an elastic or resilient bed adapted to be broughtV into engagement with: a shoe sole to cause pressure l0 to be exerted against the shoe sole while the cement employed in fastening the sole tothe upper4 is drying;

Another object of the invention is to providel a form of screw press adapted to be used in conjunction with the band press disclosed in my prior patent, for increasing the amount ofpressure exerted against the shoesole' by the bands of the band press.

further obj ect of the invention is to provide a screw press having a resilient bed, which is of simple and durable construction, and in which the parts adapted to become Worn, or to lose their eiiiciency in the course of time, may be easily and quickly replaced.

With the foregoing and other objects, whichvwillbe made manifest in the following detailed'y description and specifically pointed out'in the appended'claims, referenceis had tothe accompanying drawings for an illustrative-embodiment of the invention, where- Fignrefl is a top plan'view of the'improved rubber band cushionshoe sole press,

4.0 Referring to the accompanying drawings,

wherein similar-reference characters designate similar parts throughout, the device consists of a work holding device, generally designatedias 10, consisting of base plate 1l,

on which there-is a web 12. Adjacent to one end-of web 12 Jthere is a shank 13, preferably provided with lateral reinforcing ribs 14. The shank on its lower end is formed to provide a: slice last shape 15 on which a shoe S isfadapted to be mounted. On the edge of 1928. Serial No. 292,225.

the web 12 there are formed' a plurality of notches 16, which are wider on their inner ends than at their entrances. A corresponding number of elastic rubber bands 17 are positioned in the notches 16 and are adapted 156 to bestretched over the shoe sole 18, which is to be applied to shoe S. Small metal plates, not shown, are disposed between the rubber bands' 17 and the entrance to the notches, so that the bands when stretched will not bey pulled through the notches. One or more notches or recesses 19 may be formed on the back of shank 13, and which are adapted to receive rubber bands which can also be stretched over the shoe sole 18. .Q5

Vhen these rubber bands are stretched over the shoe sole 18, it will be understood that they will eXertapressure on the shoe sole, urging it against the upper, and against the shoe last shapel 15. Oneend of the base plate 11 is provided with a screw clamp 20 for mounting or fastening the work holding device on a table, or suitable support, while the shoe S is being positioned thereon and the elastic bands 17 are being stretched and positioned.

The construction of the work holding device as abo-ve described is they same as that disclosed in my prior patent above referred to.

The construction of the'press is as follows: The vpress consists of a rectangular bed'frame, having longitudinal side bars 21, connected by end membersI 22, and intermediate cross member23 connects the side bars intermedi- 85 ately with their ends. This bed frame is supported by legs 24:, arranged at its corners. Ayoke 25is mountedion the bed frame thus Vprovided andy has its sides provided at their lower ends with horizontal supporting bars .26, having hooked ends 27, which receive flanges 28v at the corners of the bed frame. Screws 29 are threaded through the ends of thesupporting bars 26 and are tightened into engagement with the flanges, so that the k yoke 25 is removable, but firmly supported upon the bed frame. Two screws 3() and 31 extend through the top of the yoke 25 `and have a threaded engagement therewith.

These screws are provided at their upper 10 side thereof there is formed an arm 36 and. this arm, together with the opposed sides of the yoke 25, has guide r-ibs*37',kr whichare receivable in notches or recesses in` the ends ofthe followers 34 and 35, guiding the followers in a vertical movement withoutV rotation. On the followers 34 and 35 there are.

indicating arrows 38, Ywhich point toward lindicia 39 on `the arm 36. V.A resilient or elastic bed is formed on the bed frame by a series of rubber bands 40, which are slipped over the ends of the bed frame and are positioned side by: side on the longitudinal sidebars 21.

A similar. set of flat rubber elastic bands 41 i isr stretched and slipped over the side Vbars of the frame and are positioned side by side on the vend members of: the lbed frame over the bands40. This second series of bands is positioned in place before the' yoke 25 is mounted on the bed frame and as the positions of the supporting bars 26 intermediate y Y their ends are spaced from the end members ofthe bed frame as shown in Fig, 1.these supporting bars 26 inno way interfere with either of the sets of bands. In the preferred :form of: construction additional` bands 42, which are somewhat wider than the bands of either series, are positioned or stretched on the bedV framevand extended transversely across it beneath screws 30 and 31. The operation of the device is as follows:

TheV work holding device 10 isfirst mounty led in a position inverted from that shown in Fig. 2 on aitable or support. The work, which ist-he shoe S, is then applied to the shoe-last shape 15 and the shoe sole 18 is then applied with cement. The rubber bands 17 are then stretched and caused to assume the f positionshown in Fig.'2, exterting a pressure on the shoe sole, which is more or less evenly distributed.` It'lis highly 'desirableto' have the pressure much 'greater than thatV which lso canbe Vexerted by the bands "17 in many instances andin suchY cases the work holding device is removed from the table bv loosening the screw clamp 2() andpositioned on the bed of the press as shown in Figf2, with the base plate 11 beneatha follower 'and the portion of the rubber bands '17 across theI shoe `sole 'resting on a han d 42 on 'th ebed frame; When in this positionrthe hand wheel is rotated,l

`forcingits follower downward into engage- Yment with plate 11: 4Thisc ausesban d 42 and -ban ds 40 and 41 to'rbe flexeddownwardly.causing them 4to be stretcliedand to increasethe. pressure exerted on the-shoe sole'18 by the Y bands 17. When 'in this positiontheiiidicat- .ing arrow 38 on`- the followerfindicates ap- .Y proximately the pressure exerted bythe elas- V35 ticban'd on the shoe sole. The device' is 'al- Vlrand 31 with their respective followers 34 and 35, two work holding devices 10 with their 'respective shoes may beV simultaneously mounted thereon, so that both will be finished atjthe same time.

If during the vcourse of time any of the bands on the bed frame should deteriorate or lose their elasticity they can'be easily and quickly 'replaced on loosening the screwsf29 and removing the yoke 25. c The-cross bar 23 Vdividesthe bed frame into tworectangles, over `which the upper portions of the bands 4() and 41- are arranged. In this manner the bed frame is divided into two parts, the elastic'means on ,each part being operable to a certain extent independently of the other as shown on Fig. 3. f
